In this paper, we propose a modular security approach using a positioning security engine featuring GPS location features that can uniquely identify the IoT user device. We propose the modular security scheme to reinforce the security and viability of IoT-centric solutions for various innovative applications, including IoT Mobile payment, Smart city heterogeneous networks, communication services, safety, and locationbased services integration. To achieve our goal of securitization and viability we target consumer IoT devices equipped with built-in locationbased GPS chips, which are vulnerable to hackers where the existing cryptographic authentication-based protocols demand power and computation resources required for authentication protocols is not sufficient to carry end to end secure transaction in an IoT environment. Therefore, to compensate this lack of environment capability to carry the end-to-end secure transaction on IoT devices, we implement a modular security approach method to offer the security environment the consumer IoT devices require when emitting various radio signals. Moreover, the implementation of our security engine has a purpose to offer optimal security facilitated by Simple Public Key Infrastructure (SPKI) following the Pretty Good Privacy (PGP) Web of Trust (WoT) approach. Our implementation of the security engine on the development board Arduino succeeded in providing and extended secure capable environment for carrying secure transactions. Our results show 70, 80 and 90 percent communication success between Security Engine modules with 70 percent of successful SSL secure key exchange by every identified user in best 15 seconds simulation time for two by third round of simulation.
